Blueberry plant, ‘NS 13-6’

ABSTRACT

A new and distinct variety of blueberry plant, which is denominated varietally as ‘NS 13-6’ is described, and which produces a fruit having a medium to large fruit size, a high to very high fruit sweetness, a firm fruit, a low to medium fruit acidity, and displaying a small dry picking scar, and an extremely high yield, when grown under the ecological conditions prevailing near Yanchep Springs, Yanchep, Western Australia.

Latin name: ‘Ericaceae Vaccinium Hybrid’.

Varietal denomination: ‘NS 13-6’.

BACKGROUND OF THE NEW VARIETY

The present invention relates to a new, novel, and distinct variety of blueberry plant ‘Vaccinium Hybrid’ and which has been denominated varietally as ‘NS 13-6’.

ORIGIN AND ASEXUAL REPRODUCTION OF THE NEW VARIETY

The present, new variety of blueberry plant resulted from an ongoing development program of plant breeding. The purpose of this program was to improve the commercial quality of various plant varieties by creating, and releasing, promising selections of plants, including blueberries. To this end, I have made both controlled, and hybrid cross-pollinations each year to produce resulting plant populations from which improved progenies are evaluated and selected.

The new blueberry plant ‘NS 13-6’ was derived from a controlled cross-pollination, employing the blueberry plant ‘7-26’ (unpatented), which is the seed parent, and blueberry plant ‘8-10’ (unpatented), which is the pollen parent, during the 2012 growing season. This first cross-pollination took place at my property, which is located at Yanchep Springs, Yanchep, Western Australia. The seed parent ‘7-26’ is characterized, at least in part, by a semi-upright growth habit, a medium vigor, an early season ripening date, and further produces large sized, medium firmness, high sweetness, and low acidity fruit. The pollen parent ‘8-10’, on the other hand, is characterized, at least in part, by a semi-upright growth habit, a strong vigor, an early ripening date, and further produces large sized, firm, high sweetness, and medium acidity fruit. The seed derived as a result of the first cross-pollination from the seed parent, blueberry plant ‘7-26’, produced approximately 700 plants. These new plants were then grown at my aforementioned property, and the first fruit was evaluated during the 2013 growing season. Further, additional assessments of these same new plants, which took place in 2013 and 2014, resulted in the new variety ‘NS 13-6’ being selected for further asexual reproduction and evaluation. The present, new variety showed desirable traits suitable for a commercial blueberry variety. The present, new variety was asexually reproduced by cuttings, and the plants produced from this first asexual propagation were again evaluated during the 2015 and 2016 growing seasons. The asexually reproduced plants, which were produced from the aforementioned asexual reproduction process, were subsequently evaluated, and were found to be true to the original plant. It was my conclusion, at that time, that the variety ‘NS 13-6’, was a new, novel, and distinct variety of blueberry plant.

In relative comparison to two of the closest known varieties, that being the ‘EB 8-42’ blueberry plant (U.S. Plant Pat. No. 25,858), and ‘EB 12-19’ blueberry plant (U.S. Plant Pat. No. 27,142), the new variety of blueberry plant is clearly distinguishable. The present, new variety is distinguishable from the ‘EB 8-42’ blueberry plant (a closest known variety) in view of its bush, which expresses a strong growth vigor when compared to the bush of the ‘EB 8-42’ blueberry plant, which expresses a medium to strong growth vigor. Further, the present, new variety is distinguishable from the ‘EB 8-42’ blueberry plant in view of the fruit it produces, which possesses a high to very high fruit sweetness when compared to the fruit produced by the ‘EB 9-42’ blueberry plant, which produces fruit having a medium to high fruit sweetness. Still further, the present, new variety is distinguishable from the ‘EB 8-42’ blueberry plant (a closest known variety) in view of the fruit it produces, which possesses a medium to large fruit size when compared to the fruit produced by the ‘EB 8-42’ blueberry plant, which produces fruit having a large fruit size. Yet further, the present, new variety is distinguishable from the ‘EB 8-42’ blueberry plant (a closest known variety) in view of its bush, which produces flowers and fruit on the 1-year old shoots only when compared to the bush of the ‘EB 8-42’ blueberry plant, which produces flowers and fruit on the current year's shoots and the 1-year old shoots.

The present, new variety is distinguishable from the ‘EB 12-19’ blueberry plant (a closest known variety) in view of the fruit it produces, which is firm when compared to the fruit produced by the ‘EB 12-19’ blueberry plant, which produces very firm fruit. Further, the present, new variety is distinguishable from the ‘EB 12-19’ blueberry plant in view of the fruit it produces, which possesses a low to medium fruit acidity when compared to the fruit produced by the ‘EB 12-19’ blueberry plant, which produces fruit having a low fruit acidity. Still further, the present, new variety is distinguishable from the ‘EB 12-19’ blueberry plant in view of the fruit it produces, which possesses a medium to large fruit size when compared to the fruit produced by the ‘EB 12-19’ blueberry plant, which produces fruit having a large to very large fruit size. Yet further, the present, new variety is distinguishable from the ‘EB 12-19’ blueberry plant (a closest known variety) in view of its bush, which produces flowers and fruit on the 1-year old shoots only when compared to the bush of the ‘EB 12-19’ blueberry plant, which produces flowers and fruit on the current year's shoots and the 1-year old shoots.

The present, new variety is distinguishable from the ‘7-26’ blueberry plant (the seed parent) in view of its bush, which expresses a strong vigor when compared to the bush of the ‘7-26’ blueberry plant, which expresses a medium vigor. Further, the present, new variety is distinguishable from the ‘7-26’ blueberry plant in view of the fruit it produces, which possesses a high to very high fruit sweetness compared to the fruit produced by the ‘7-26’ blueberry plant, which produces fruit having a high fruit sweetness. Still further, the present new variety is distinguishable from the ‘7-26’ blueberry plant in view of the fruit it produces, which is firm when compared to the fruit produced by the ‘7-26’ blueberry plant which produces fruit having a medium firmness. Additionally, the present, new variety is distinguishable from the ‘7-26’ blueberry plant (the seed parent) in view of the fruit it produces which possesses a medium to large fruit size when compared to the fruit produced by the ‘7-26’ blueberry plant, which produces fruit having a large fruit size. Moreover, the present, new variety is distinguishable from the ‘7-26’ blueberry plant in view of its time of beginning of flowering on one-year-old shoots which is late April to early May when grown under the ecological conditions present near Yanchep Springs, Yanchep, Western Australia, when compared to the time of beginning of flowering on one-year-old shoots of the ‘7-26’ blueberry plant, which is in late June to early July when grown under the ecological conditions present near Yanchep Springs, Yanchep, Western Australia. Yet further, the present, new variety is distinguishable from the ‘7-26’ blueberry plant (the seed parent) in view of its time of beginning of fruit ripening on one-year-old shoots which is in August when grown under the ecological conditions present near Yanchep Springs, Yanchep, Western Australia, when compared to the time of beginning of fruit ripening on one-year-old shoots of the ‘7-26’ blueberry plant, which is September when grown in the same ecological conditions present near Yanchep Springs, Yanchep, Western Australia. Even further, the present, new variety is distinguishable from the ‘7-26’ blueberry plant (the seed parent) in view of its bush, which is evergreen when compared to the bush of the ‘7-26’ blueberry plant, which has a bush that is semi-evergreen.

The present, new variety is distinguishable from the ‘8-10’ blueberry plant (the pollen parent) in view of the fruit it produces, which possesses a high to very high fruit sweetness when compared to the fruit produced by the ‘8-10’ blueberry plant which produces fruit having a high fruit sweetness. Further, the present, new variety is distinguishable from the ‘8-10’ blueberry plant in view of the fruit it produces, which possesses a low to medium acidity when compared to the fruit produced by the ‘8-10’ blueberry plant, which produces a fruit having a medium acidity. Still further, the present, new variety is distinguishable from the ‘8-10’ blueberry plant (the pollen parent) in view of the fruit it produces, which possesses a medium to large fruit size when compared to the fruit produced by the ‘8-10’ blueberry plant, which produces fruit having a large fruit size. Moreover, the present, new variety is distinguishable from the ‘8-10’ blueberry plants, in view of its time of beginning of flowering on one-year-old shoots which is late April to early May when grown under the ecological conditions present near Yanchep Springs, Yanchep, Western Australia, when compared to the time of beginning flowering on one-year-old shoots of the ‘8-10’ blueberry plant, which is June when grown under the ecological conditions present near Yanchep Springs, Yanchep, Western Australia. Yet further, the present, new variety is distinguishable from the ‘8-10’ blueberry plant (the pollen parent) in view of its time of beginning of fruit ripening on one-year-old shoots, which is August when grown under the ecological conditions present near Yanchep Springs, Yanchep, Western Australia, when compared to the time of beginning of fruit ripening on one-year-old shoots of the fruit produced by the ‘8-10’ blueberry plant, which is of October when grown under the ecological conditions present near Yanchep Springs, Yanchep, Western Australia. Even further, the present, new variety is distinguishable from the ‘8-10’ blueberry plant (the pollen parent) in view of its bush, which is evergreen when compared to the bush of the ‘8-10’ blueberry plant, which has a bush that is semi-evergreen.
